UL (Underwriters Laboratories)

UL (Underwriters Laboratories)

The organization mainly evaluates products, components, materials and systems that have to meet specific requirements. Once meeting the required standards, they are allowed to use the (paid) UL logo on the products. UL maintains a directory with more than 3 million products being publicly available on its online databases. To obtain the certification by UL certain safety requirements, which are largely developed by UL itself, needs to be verified.

Furthermore, manufacturers have to ensure that each copy of its products meet the specified security requirements (with the help of an appropriate system). UL inspects at regular intervals unannounced checks on the production of the manufacturer to ensure they comply with the requirements permanently. If the product design has changed, UL first reviews and approves then the new version before the product is provided with a UL mark.
